BRICK.

$PEGIFIGATION forming part of Letters Patent No. 733,069, dated July 7,1903. Application filed October 2, 1902. Serial No. 125,635. (No model.)

facing of material of other kind than th' body, such facing, forinstance, to be of glass or porcelain or analogous material.

The object of my invention is to form the brick with a facing at one andthe same operation, thus forming the whole an integral piece without thenecessity of using a cement of any typeto secure the facing to the bodyof the brick. This results in a cheap construction, a solid structure,and a brick in which the face cannot by any possibility become detached.

In the drawings, Figure I is a view in side elevation, illustrating abrick constructed according to my invention, showing the same partly insection for the purpose of illustrating attaching-lugs formed with thefacing. Fig. II is a cross-sectional view illustrating the manner inwhich the brick is formed or may be formed. Fig. III illustrates a brickformed according to my invention in which the facing is made to extendslightly beyond the body of the brick, so that when the bricks areplaced side by side space is left between the contiguous body for mortaror cement, while the faces are joined or abut. Figs. IV, V, and VIillustrate modifications of lugs which may be employed in connectionwith the facing to act as keys for retaining the facing to the body. I

A represents the body of the brick, which is formed of cement which willdry with sufficient hardness to produce a very firm compact body. Thiscement is composed, preferably, of a mixture of ordinary cement and sandin proper proportions, which may be varied, and other ingredients may beadded to the ingredients before mentioned as found necessary ordesirable.

B representsthe facing, which is composed, preferably, of glass orvitreous substance.

a plunger (1.

This facing B is preferably provided with lugs 12 b soconstructed andarranged, as shown in Fig. I or in Fig. V modifications, as to form akey when the body is cast or pressed thereon. These projections 12 b maybe of any desirable form and of any suitable facing,'provided they areadapted to perform the just aforementioned function.

In forming the brick I take a facing B, place it in the mold facedownward, as illustrated in Fig. II, pour the body A into the mold, andpress the same firmly by means of This plunger, mold, and pressingmechanism may be of any suitable construction and operated either singlyor in gangs. After the body A is pressed firmly in place it is removed,with the facing, from the mold and after it has set a short time isallowed to dry. In drying, the material contacts, so as to bind thefacing firmly to the body, and no kiln-dryingis necessary. When thefacing A projects beyond the edge of the body, as illustrated in Fig.III, the process is the same in forming it; but the mold should beformed as suggested by dotted lines in Fig. II, so that the brick may beremoved therefrom.

The brick as above constructed has great advantages over bricks in whichthe face is secured to the body subsequent to the forming of the body bya cement, first, from a standpoint of economy in labor and material;second, the structure is integral, and no liability is had of the facingparting from the body, as the body is pressed to the facing during themanufacture of the brick. The structure is also more firm as far as itsbody portion is concerned than the ordinary brickbody and will holdmortar or cement better than the ordinary brick, and when the brick isformed for an interior facing or for an exterior facing the facing as awhole has the appearance of a uniform polished solid struc-- ture.

The facings B may be made ornamental in color or design, if desired, andwhen the design is altered it is only necessary to form the bottom ofthe mold upon which the face rests as a fallow-board to sustain theface.

What I claim is- A brick comprising a facing carrying lugs on its rearside, said lugs having contracted ICO portions, and abodyportion ofcement applied hoga and State of Ohio, this 22d day of Septo said rearside of the facing While in aplaste1nb er, 1902. tic state whereby thecement may engage in said con tracted portions of the lugs and formMICHAEL MURPHY 5 a locking engagement therewith when the eement is in ahardened state.
